Exception on connection

[Jens Melzer]

After setting up a client (one computer) and a server (another computer), we get the following error message when testing the connection:

Error: An unexpected error occurred running the preview Grpc.Core.RpcException: Status(StatusCode="Unauthenticated", Detail="Remote address 'ipv4:10.5.0.133:61053' is not allowed access", DebugException="Grpc.Core.Internal.CoreErrorDetailException: {"created":"@1681289797.917000000","description":"Error received from peer ipv4:10.5.0.148:5002","file":"..\..\..\src\core\lib\surface\call.cc","file_line":1067,"grpc_message":"Remote address 'ipv4:10.5.0.133:61053' is not allowed access","grpc_status":16}") at Grpc.Core.Internal.ClientResponseStream`2.MoveNext(CancellationToken token) at Omada.ODW.Staging.PreviewService.Clients.StatefulHostingServiceClient.ImportData(ImportRequestData requestData) at Omada.ODW.Staging.PreviewService.Preview.GRpcQueryCollectorWrapper.Query(QueryAndMappings queryAndMappings, Guid token, Int32 batchSize) at Omada.ODW.Staging.Stager.QueryAndStage(String queryAndMappingsXml, IStageReceiver receiver, Int32 batchSize, Boolean stageMappedResult) at Omada.ODW.Staging.PreviewService.Preview.Previewer.PreviewQuery(String query, Dictionary`2 parameters, PreviewOptions options, String requestCorrelationId, HostingServiceConnectionDetails connectionDetails) (ref. no. 3CAD3F13)

Who says what and what can we do?

Please review this guide on gRPC authentication: https://grpc.io/docs/guides/auth/

More information on your setup (i.e. what authentication method you are using, gRPC version, etc) would also be helpful.
